Modelling the kinetics of seedless guava(Psidium guajava L.) peroxidase inactivation due to heat and thermosonication treatments.

Effect of heat and thermosonication on inactivation kinetics of peroxidase in seedless guava have been studied over a temperature range of 80-95°C. Application of thermosonication was studied at 25, 50 and 75% of radiation intensity at the same temperature range. Ultrasonic wave’s intensity had sig...
